Under the "Total Force" concept, Montana Air National Guard units are considered to be Air Reserve Components of the United States Air Force. Montana ANG units are trained and equipped by the Air Force and are operationally gained by a Major Command of the USAF if federalized. In addition, they are assigned to Air Expeditionary Forces and are subject to deployment tasking orders along with their active duty and Air Force Reserve counterparts in their assigned cycle deployment window. Along with their federal obligations, Montana ANG elements are subject to activation by the Governor to provide protection of life and property, and preserve peace, order and public safety. State missions include disaster relief in times of earthquakes, hurricanes, floods and forest fires, search and rescue, protection of vital public services, and support to civil defense.
Components
The Montana Air National Guard consists of the following major unit:
On 24 May 1946, the United States Army Air Forces, in response to dramatic postwar military budget cuts imposed by President Harry S. Truman, allocated inactive unit designations to the National Guard Bureau for the formation of an Air Force National Guard. These unit designations were allotted and transferred to various State National Guard bureaus to provide them unit designations to re-establish them as Air National Guard units. Lt. Col. Willard Sperry, a decorated combat pilot, began building the Montana Air National Guard at Gore Field, Great Falls. On 27 June 1947, the 186th Fighter Squadron was activated and federally recognized. Within two weeks, six F-51D Mustangs arrived. Its mission was the air defense of the state. 18 September 1947, however, is considered the Montana Air National Guard's official birth concurrent with the establishment of the United States Air Force as a separate branch of the United States military under the National Security Act. On 1 July 1955 the 186th Fighter-Interceptor Squadron was authorized to expand to a group level, and the 120th Fighter Group was allotted by the National Guard Bureau, extended federal recognition and activated. Today the Montana ANG performs an airlift mission, equipped with C-130 Hercules Transport Aircraft. After the September 11th, 2001 terrorist attacks on the United States, elements of every Air National Guard unit in Montana has been activated in support of the Global War on Terrorism. Flight crews, aircraft maintenance personnel, communications technicians, air controllers and air security personnel were engaged in Operation Noble Eagle air defense overflights of major United States cities. Also, Montana ANG units have been deployed overseas as part of Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq as well as other locations as directed.
